react-hooks's Introduction

react-hooks

React Hooks API 在低版本 React 16.6 下面的一个实现,可以在不升级 React 版本的前提下体验新的 React Hooks API。

Install

npm install blx-react-hooks
# or
yarn add blx-react-hooks

Usage

在声明函数式组件的时候,通过用 withHooks() 函数封装��就可以就使用 Hooks API 了。与 React 的 Hooks API 只差了需要 withHooks() 函数进行封装。

import {withHooks, useState} from 'blx-react-hooks'

// 如果想在调试的时候看到组件名,定义�function的时候必须要定义成一个命名函数
const Counter = withHooks(function Counter({title, initCount}) {
  const [count, setCount] = useState(initCount)
  return (
    <div>
      <h1>{title} </h1>
      <button onClick={() => setCount(count - 1)}> - </button>
      Count: {count}
      <button onClick={() => setCount(count + 1)}> + </button>
    </div>
  )
})
